Black sweet cherry (Prunus serotina) is a deciduous woody plant species that produces edible berries. This medium-sized forest tree is a sunlight loving species that is often found growing in old, open fields. This is a long lived tree species with ages recorded as old as 258 years! The wilted leaves and seeds of the fruit contain cyanide enzymes that prove poisonous to animals that may forage upon them. While the fruit flesh is safe to consume, it is not recommended to plant near livestock lots or pastures.
